FIRIE-EXTIVNGUCIFSHER.

SPECIFICATION forming part of Letters Patent No. 761,726, dated June *7,1904.

Application filed February 12, 1904. Serial No. 193,328. (No model.)

To ctZZwhom it may concern.

ers, of which the following is a specification. My invention relates tofire-extinguishers of the class which are employed in putting out fieldor ground fires; and it consists in certain novel features ofconstruction, arrangement,

andcombination of parts, which will be readily understood byreference tothe description of the accompanying drawings, forming a part iof thisapplication, and to the claims hereto 1 appended, and in which myinvention is clearly pointed out.

Figure 1 of the drawings is a plan of a firethe same'on line A A onFigs. 1 and 3. Fig. 3 is an end elevation looking at the left end ofFig. 1. Fig. 1 is an end elevation looking at the right end of Fig. 1,and Fig. 5 is a transverse section illustrating amodification.

In the drawings, 1 1 are two spoked wheels mounted loosely on the shaft2, said wheels being connected together by suitable stayrods 3 tomaintain them at a proper distance apart, and a wirernetting covering1'is wrapped around said wheels and extends from one wheel to the otherin the form of an openwork cylinder, said netting being secured togetherat its longitudinal edges and also firmly secured to the circular rim ortire of said wheels in any suitable manner. An outer covering 5, of feltor aloosely-woven asbestos fabric, is wrapped about and firmly securedto said netting.

The shaft 2 has firmly secured thereon, so as to be movable therewithabout the axis of said shaft, a metal cylinder 6, one head of which isset a short distance inside of the end of the barrel of said cylinder toform a panlike recess 7 to facilitate the filling of the said cylinderwith water or other liquid.

The cylinder 6 has its bearings on the shaft 2 slightly above thecenters of its eads,

whereby said cylinder will be maintained automatically in its normalposition when not in operationthat is, with the discharge-orifices 8arranged in a longitudinal row or rows along one side thereof uppermost.The

. chambered end of said cylinder 6' is provided with a feed-orifice 9,which communicates with the elbow-pipe 10, located just inside of saidrecessed head, and extends from said feedorifice nearly to the oppositeside of the bar rel of said cylinder, as shown in full lines in Fig. 2and in dotted lines in Fig. 3.

I One end of the shaft 2 has firmly secured thereon outside of a wheel 1a lever 14, as shown in Figs. 1 and 4. Theshaft 2 also i has looselymounted on each end thereof one 5 arm of a forked pole or handle 11,made, prefextinguisher illustrating my invention with a portion of theoutside covering of the main drum and the wire-netting support thereforbroken away in order to moreclearly show other parts. Fig. 2 is alongitudinal section of erably, in three parts, bolted together, asshown in Figs. 1, 3, and 4:.

The operation of my invention is as follows: The machine is first turnedup so as to rest upon its right-hand end. Water or other thefeed-orifice 9-and the pipe 10 till the cylinder 6 is filled, when themachine is turned down upon its side and the cylinder 6 assumes itsnormal position, with its heaviest portion below the axis of its-shaft 2and the perforations 8 at thetop or upper side of said cylinder. Theoperator then seizes the handle and pushes the machine toward the fire,the "covered drum rolling on the ground while the cylinder 6 maintainsits normal position.

-When'the vicinity of the fire is reached, the

operator imparts a half-revolution to the cylinder 6 by moving the lever14 from its posialongside of an arm of the forked pole or handle 11 andsecures said lever 1 1 to said arm by a pin (not shown) inserted throughthe'holes 15 and 16, formed, respectively, in the. arm of the handleandin the end of said lever. cylinder will be discharged, through theorifices 8, into the annular space between the cylinder 6 and the wallof the main drum, thereby thoroughly saturating the felt or asbestoscovering 5, the quantity of liquid discharged from said cylinder beingproportioned to the fire-extinguishing liquid is then poured into thepan-like recess 7 and will flow through tion shown in Figs. 1 and 4 to aposition When this is done, the water in the size and number of theorifices 8. The machine with its covering so saturated and with more orless liquid percolating through said covering being rolled over aground-fire will effectually extinguish the same.

Instead of hanging the cylinder 6 out of center it may be mounted inbearings concentric with its axis, and the side of said cylinderopposite to the discharge-orifices may be weighted by securing therein abar of metal 18 of suitable capacity to insure said cylinder beingnormally maintained in a position with its discharge-orifices at its topside, as illustrated in Fig. 5.

WVhat I claim as new, and desire to secure by Letters Patent of theUnited States, is'

1. In a fire-extinguisher, the combination of a hollow drum thecircumferential shell of which is composed of an open-work metalstructure and an outer covering of porous textile fabric preferablyasbestos, and adapted to roll upon the ground; a shaft having hearingsin the heads of said drum; a liquid-receiving tank firmly secured uponsaid shaft, and provided on one side with a series of dischargeoriiicesdistributed longitudinally along one side thereof; means for normallyholding said tank, with its perforated side uppermost; means forreversing said tank and securing it in said reversed position; and meansby which the machine may be propelled over the burning ground.

2. In a fire-extinguisher, the combination of a supporting-drum having aporous peripheral wall and wheel-like heads mounted loosely on a shaftor journals; a liquid-receiving cylinder provided with a series ofdischarge-orifices distributed longitudinally along one side thereof; ajournal secured to and projecting outward from each head of saidcylinder and fitted to bearings in the heads of said drum; areversing-lever lirmly secured on one of said journals; a pole oroperating-handle mounted loosely on said journals; and means forsecuring said reversing-lever and pole together as and for the purposesset forth.

8. In a lire-extinguisher, the combination with a revoluble drum havinga porous pcripheral wall; of a liquid-receiving cylinder provided witheccentric journals on its ends fitted to axial hearings in the heads ofsaid drum, and with a pan-like recess or chamber in one end thereof, anda series of perforations distributed longitudinally along one sidethereof; and a supply-pipe extending transversely across the interior ofsaid receivingcylinder, and communicating at one end with the pan-likechamber 7, and open at its other end to the interior of said cylinder.

4. In a fire-extinguisher, the combination with a revoluble drum havinga porous peripheral wall, and means for propelling said drum along theground, of a liquid-receiving cylindrical tank having journals litted tobearings in the heads of said drum, and provided with a series ofdischarge-orifices distributed longitudinally along one side thereof,said tank being so constructed and arranged that the preponderance ofweight thereof shall be upon the side of its axis opposite to saiddischarge-orifices as and for the purposes set forth.

In testimony whereof I have ailixed my signature in presence of twowitnesses.
